An oil tanker that caught fire after colliding with a freighter off China's east coast is at risk of exploding and sinking, Chinese state media reported on Monday, as authorities from three countries searched for 32 missing crew members and contain oil spewing from the blazing wreck.

State broadcaster China Central Television, citing Chinese officials, said none of the 30 Iranians and two Bangladeshis who have been missing since the collision late on Saturday had been found. Search and clean-up efforts have been hampered by fierce fires and poisonous gases that have engulfed the tanker and surrounding waters, CCTV reported.

The Panama-registered tanker Sanchi was sailing from Iran to South Korea when it collided with the Hong Kong-registered freighter CF Crystal in the East China Sea, 257 kilometers (160 miles) off the coast of Shanghai, China's Ministry of Transport said.

China, South Korea and the US have sent ships and planes to search for the Sanchi's crew, all of whom remain missing. The US Navy, which sent a P-8A aircraft from Okinawa, Japan, to aid the search, said late Sunday that none of the missing crew had been found.

All 21 crew members of the Crystal, which was carrying grain from the United States to China, were rescued, the Chinese ministry said. The Crystal's crew members were all Chinese nationals.

Kwon Yong-deok, a Korea Coast Guard official, said thick black smoke was still billowing from the ship on Monday afternoon and bad weather was worsening visibility at the scene.

The Sanchi was carrying 136,000 metric tons (150,000 tons, or nearly 1 million barrels) of condensate, a type of ultra-light oil, according to Chinese authorities, who have dispatched three ships to clean the spill.

But the size of the oil slick from the Sanchi — and the scale of the environmental toll — may be smaller. Unlike the thick crude that gushed out of the Valdez, much of the light, gassy condensate from the Sanchi may have evaporated or burned immediately, Mr Kwon said.

The Sanchi's own fuel that leaked during the collision will be more difficult to clean, officials said.
